Zooming feature

[Youfei Chen]

Hi

I'm trying to figure out if I could get zooming boundaries, such as the boundaries of the orange rect. The reason I’m doing that is I need to update series by providing data from a different source if the user reaches a certain level. Thus I cannot just use Syncfusion zooming directly.

Also, is it possible to block Syncfusion zooming feature but still able to use zooming UI?

Hi Youfei,

Thanks for using Syncfusion products.

1) Is it possible to block Syncfusion zooming feature but still able to use zooming UI?

We suggest you to set “false” value to “EnableXZooming” and ““EnableYZooming” properties of chart control to block the zooming feature in UI. If your intention is to zoom the chart control based on certain range (user give the range values for zoom) value, you can use the “ZoomRange” method of axis to zoom the chart control by certain range values. Please refer the below code snippiet to achieve this.

[C#]

//Block zooming feature via UI
this.chartControl1.EnableXZooming = false;
this.chartControl1.EnableYZooming = false;

//Zoom range method to zoom the chart control by certain range
this.chartControl1.PrimaryXAxis.ZoomRange(new DoubleRange(3,5));
this.chartControl1.PrimaryYAxis.ZoomRange(new DoubleRange(200, 400));

Please let me know if we misunderstood your query please provide us some clear details or screenshots about your requirement.
